A Trojan Horse Virus is a type of malicious software that disguises itself as a legitimate program to trick users into downloading it. Just like the ancient Greek story of the Trojan Horse, where the Greeks hid soldiers inside a wooden horse to infiltrate the city of Troy, this virus pretends to be harmless. Once installed, it can steal personal information, damage files, or allow hackers to access your computer. To protect yourself from a Trojan Horse Virus, always be cautious about downloading software from unknown sources. Keeping your antivirus software updated and regularly scanning your computer can help detect and remove these threats before they cause harm.
